Different body cells can respond differently to the same hormones because
A) different target cells have different sets of genes.
B) each cell converts that hormone to a different metabolite.
C) target cells responses are determined by the components of their signal transduction pathways.
D) the circulatory system regulates responses to hormones by routing the hormones to specific targets.
E) the hormone is chemically altered in different ways as it travels through the circulatory system.

Question

Quizplus · Accepted Answer

Different body cells can respond differently to the same hormones because target cell responses are determined by the components of their signal transduction pathways. Each target cell has a different set of proteins, enzymes, and second messengers that translate the hormone signal into a cellular response. These differences in signal transduction pathways can also explain how the same hormone can have different effects in different tissues or in different physiological contexts.
